Columbia Responds to Upcoming Diverging Diamond Interchange

COLUMBIA - The construction project at Stadium Boulevard and Interstate 70 will add a diverging diamond interchange in Columbia.

Some Columbia residents are worried that a diverging diamond interchange could be difficult to understand and adapt. MoDOT has released pictures and descriptions on its website to explain how to navigate a diverging diamond interchange:

  • Motorists traveling on Stadium will cross over to the opposite side of the road at the first traffic signal
  • After driving over I-70, they can either turn left to access I-70 or travel through the second signal to cross back over and continue on Stadium
  • Motorists entering the interstate do not have to cross opposing traffic

Kevin Hollins, a resident living two miles away from the intersection, said it would be great once it is finished, although it is a little annoying right now.

"Once it is done, it should ease a lot of the congestions around here, which has been a major problem for awhile," Hollins said.

Hollins said he moved to Columbia from San Diego, California six years ago. He said as Columbia grows, we have to adapt to be more like a bigger city and take on similar projects that they do there.

"The traffic will cause some irritations, but we have to realize that in the long run it is the best for the city," Hollins said.

According to MoDOT, the new intersection should be completed by the fall of next year. The project has closed roads and lanes, limiting space for drivers. The closings increase congestion and can cause traffic to come to a standstill, especially during the morning commute.
